Marsha's Born Free's a female Class C. As mentioned, it's one thing to raise the rear of a tow vehicle. On a Coach, permanently raising one end causes leveling problems once at the campsite. We had a 24-ft C that was sagging low and raised the rear with what was essentially helper springs. Then we were a couple inches above level in the rear so we knew we'd have to raise the front to be level on a level site. If airbags will really provide 2" of lift at the AXLE, that'll be a little more out at the very back of the coach. Might be enough. Might help keep it from jouncing down when the wheels meet the dip at the base of the driveway, too. Bigger rollers and rollers farther back are a mixed blessing. The coach is protected, but it actually gets its clearance reduced.
